Web Platform List (Not Exhaustive)
The below list contains web platforms or self-publishing services that often cause confusion on whether the series is allowed or not. It is mostly for referencing rather than a complete list of what is or is not allowed and can be expanded. Specific print and web magazines aren’t mentioned here.
If one of the below accepted links exist, please add them to the External Links. Additionally, Mavo and Pixiv, and Twitter links can still be used for eligible doujinshi.
As always, works still have to satisfy the Japanese, Chinese, Korean, or Taiwanese ‘Country Of Origin’ type.
If the work originally published on ‘Not Accepted‘ websites is later picked up by a professional publisher of the same language, that later publication would be what can be added to the database.
